iEmulator is an application provided by Weigan Technology (Shenzhen) Co., Ltd. (hereinafter referred to as "we" or "us") for retro game emulation. This Privacy Policy applies to iEmulator on iOS, iPadOS, macOS, and Android.
We attach great importance to the protection of your personal information and privacy. We will provide appropriate security measures for your personal information in accordance with legal requirements and industry-standard security practices.
This Privacy Policy works together with our User Agreement for iEmulator.
On the iOS / iPadOS build, advertising and usage-quota features apply to non-VIP users. When your detected region is mainland China, ads are served through Pangle GroMore mediation (including Pangle and Tencent Ads); in other regions, Google AdMob is used. VIP purchases are offered through Apple In-App Purchase. The macOS build does not display ads or apply daily launch quotas, but launching games requires an active VIP subscription.
On Android, Premium / VIP subscriptions and lifetime purchases are offered through Google Play Billing when distributed via Google Play or similar channels. When distributed via domestic app stores in mainland China (such as OPPO, vivo, or 360 Mobile Assistant), non-Premium / non-VIP users may see ads served through Pangle GroMore mediation (see Section 2.3); Premium / VIP purchases in those channels are handled by the respective store billing systems. Game ROMs, save data, and related information are handled primarily on your device; iCloud sync is not available on Android. We obtain your consent before initializing any ad SDK.
Welcome to iEmulator. Please read and understand our User Agreement and Privacy Policy.
Core features require storage and network permissions when you import ROMs or use linked play. Related data is processed primarily on your device.
Ad services are initialized only after you tap Agree. To display ads, measure ad performance, and prevent fraud, this app integrates third-party ad SDKs through Pangle GroMore mediation, including the Pangle Advertising SDK, Tencent Ads Android SDK, and Douyin SDK (Android). You receive 2 free game launches per day; watch a rewarded video to earn 2 more.
If you do not agree to ad-related terms, you can tap "Decline (core features only)". We will not initialize the ad SDK without your consent. In that mode, you can use basic controller settings; game launch, the game library (Calibration), and daily launch quota require agreeing to ad services.
We will only use your personal information where we have a lawful basis to do so. Under applicable law, we may process your information based on lawful grounds such as your consent, where necessary to perform or enter into a contract with you, or where necessary to comply with legal obligations.
1.1 Core app features. To provide emulation, save management, netplay, controller support, and related features, we invoke Bluetooth, microphone, local network, and iCloud capabilities through system APIs only when you use the related features (on Android, storage, network, and Wi-Fi related capabilities as applicable). On iOS / iPadOS, we may request photo-library add permission when you save in-game screenshots; on Android, screenshots are saved primarily to app storage and may be saved to your gallery if you grant permission. Game ROM files, save data, screenshots, and other content you import are processed on your device or through services you actively choose. During netplay you initiate, game data may be transferred directly between your device and other players on your local network. Optional iCloud save sync (iOS / iPadOS / macOS only) and RetroAchievements (VIP / Premium subscribers only) are offered according to each platform's capabilities. We do not use this data to build a profile that identifies you.
1.2 Local preferences. We store certain settings on your device (such as theme, usage quota counters, VIP status flags, and emulator preferences) to operate the app. This information remains on your device unless otherwise described in this Policy.
1.3 Region detection for ads (iOS / iPadOS; may also apply on Android when ads are enabled and region detection is needed). To choose the appropriate advertising provider, the app may request your country or region code from a third-party IP geolocation service (ipinfo.io). This request may expose your IP address to that service. If the request fails or no stored value exists, we may fall back to your device language (for example, Simplified Chinese maps to mainland China). The resulting region code is stored locally on your device.
1.4 Cover art lookup. To display game cover art, the app may send a cleaned game title derived from your ROM filename to third-party services such as IGDB (via Twitch OAuth) and the Apple iTunes Search API. We do not send your ROM file contents. Retrieved cover images are cached locally on your device.
1.5 Optional third-party sign-in. If you are a VIP / Premium subscriber and choose to use RetroAchievements, your username and authentication token are stored in secure device storage (Keychain on iOS / macOS; Android Keystore or equivalent on Android) and transmitted to RetroAchievements servers to sign you in and sync achievements. We do not operate RetroAchievements; its processing is governed by RetroAchievements policies.
1.6 What we do not do. We do not require you to create an in-app account. On iOS / iPadOS, non-VIP users may use core emulation features subject to usage limits. On macOS, launching games requires an active VIP subscription. On Android, core emulation does not require an account; Premium / VIP entitlements are unlocked through Google Play Billing, domestic app-store billing, or equivalent channels where applicable. We do not provide, include, or distribute copyrighted game ROM files or other third-party content through the app.
1.7 Personal information inventory. To meet applicable privacy laws and app-store compliance requirements, we disclose below the categories of personal information that iEmulator may involve. The purpose, method, and scope described for each category apply only to the versions or scenarios noted. Categories marked as "not collected" mean that our app does not actively collect, read, or upload that type of information for the stated purpose.
This section describes third-party advertising SDKs by platform. See Sections 2.1 and 2.2 for iOS / iPadOS, and Section 2.3 (including Sections 2.3.1 through 2.3.3 for each SDK) for Android builds distributed in mainland China. We obtain your consent before initializing any ad SDK.
In this scenario, the app integrates the Google Mobile Ads SDK (AdMob) to display ads (including app-open and rewarded formats), measure ad performance, and prevent fraud. AdMob is provided by Google LLC and may automatically collect information such as:
On iOS / iPadOS in the AdMob scenario described above, the app does not currently present an App Tracking Transparency (ATT) prompt before showing AdMob ads. You can limit personalized ads or reset advertising identifiers in iOS system settings (for example, Settings → Privacy & Security → Apple Advertising).
Google's privacy policy: https://policies.google.com/privacy
VIP subscribers do not see ads for features covered by their active subscription.
In this scenario, the app does not use AdMob. It initializes third-party advertising SDKs through Pangle GroMore mediation, which may serve ads from the following ad networks we have integrated:
GroMore selects and fills ad requests across these networks for the ad placements you trigger in the app. The SDKs automatically collect information such as:
SDK providers and privacy policies:
On iOS / iPadOS (mainland China region), we configure the Pangle SDK privacy provider to disable use of location for advertising. Before initializing the Pangle SDK, if the system has not yet recorded your choice, the app may present an App Tracking Transparency (ATT) prompt to determine whether IDFA may be used. If you deny or restrict tracking, we configure the SDK to limit IDFA use. VIP subscribers do not see ads.
Third-party SDKs may transmit the above information to their servers for processing and storage. Please refer to each provider's privacy policy for details.
On Android builds distributed in mainland China (such as via OPPO, vivo, 360 Mobile Assistant, or other domestic app stores), when users are not Premium / VIP subscribers or their entitlements do not cover the relevant features, the app integrates the following SDKs through Pangle GroMore mediation to display ads (including app-open and rewarded formats), measure ad performance, and prevent fraud. Ad SDKs are initialized only after you tap Agree. If you choose "Decline (core features only)", we do not initialize ad SDKs:
GroMore selects and fills ad requests across Pangle and Tencent Ads Android SDK and other integrated ad networks for the ad placements you trigger in the app. Douyin SDK (Android) is integrated as part of the Pangle / GroMore related capabilities. We obtain your consent before initializing any ad SDK. Basic information for each SDK is as follows:
Premium / VIP subscribers do not see ads. The SDKs above may transmit related information to their servers for processing and storage. Please refer to each provider's privacy policy for details.
The iOS / iPadOS and macOS builds offer VIP subscriptions and a lifetime purchase through Apple In-App Purchase (StoreKit). Payment flows are handled by Apple; we do not collect or store your full payment card numbers or other sensitive payment credentials.
We receive only purchase confirmation, subscription status, and product identifiers to unlock VIP features (such as ad-free experience on iOS / iPadOS, unlimited game launches, theme and interface customization, iCloud save sync, and RetroAchievements access) on your device. You can manage or cancel subscriptions in your Apple account settings.
Apple's handling of payment data is governed by Apple's policies: https://www.apple.com/legal/privacy/
The Android build offers Premium / VIP subscriptions and a lifetime purchase through Google Play Billing or domestic app-store billing, depending on your distribution channel. Payment flows are handled by the relevant store; we do not collect or store your full payment card numbers or other sensitive payment credentials. We receive only purchase confirmation, subscription status, and product identifiers to unlock Premium / VIP features on your device. You can manage or cancel subscriptions in your Google Play account, the Google Play Store, or the relevant domestic app store.
Google's handling of Google Play payment data is governed by Google's policies: https://policies.google.com/privacy
On iOS / iPadOS, non-VIP users may be subject to daily free launch limits and can earn additional launches by watching rewarded video ads. On macOS, launching games requires an active VIP subscription. On Android builds distributed in mainland China, non-Premium / non-VIP users receive 2 free game launches per day; watching a rewarded video earns 2 additional launches.
